Veshamru b'nai Israel et ha Shabbat. L'sot ha Shabbat l'doritam brit olam.
The Israelites are to observe the Sabbath, celebrating it for the generations to come as a lasting covenant. It will be a sign between me and the Israelites forever, for in six days the LORD made the heavens and the earth, and on the seventh day he abstained from work and rested.
